STEREOS COPIC-EXHIBITING-MAGHINE REEL.

Application filed. August 29, 1927. Seriai No. 216,013.

This invention relates to reels for stereo scopic exhibiting machinesand particularly, though not exclusively, to that type of exhibitingmachine which is operated by coins whereby the photographic cards arebrought to proper sight position; and to iniiprovements in the reelholders or-leaves; and also to the method oi? mounting the cards in thereel holders. h

The object or the invention to provide a novel and improved reel forpositively bringing the cards to proper sight position and in propersequence, whereby the opera-' tor or customer is provided with a betterand more realistic presentation than can be obtained in the ordinarymachine.

Another object of the invention. is to provide curved holders or leavesfor holding the cards so that the card when inserted in the holder willalso be curved thereby-keep ing the card in a rigid condition and pre--venting the edges or any other part of the card from curling or bendingout of shape.

Another object is to provide a reel in which the holders or arms areprovided with improved card holding means so that the cards can beeasily and quickly applied or detached and which will firmly hold thecard in opi-srative position on the holder.

And a further object is to p rovid 2a notched card which is :iulapted tobe easily mounted in the holders and held in operative position andwhich will prevent the card from shifting its position so that each cardalways maintained in proper position.

The accompanying; drawings show a selected embodiment of the inventionand the views therein are as follows: j

Fig. 1 is an elevation of my improved reel showing the manner in whichthe holders are arranged and the various positions the hold-' ers attainduring the operation of the machine. n

Fig. 2 is a top plan view of one of the holders. I

Fig. 3 is a side view thereof.

F g. 8 is a detail section on line 88 oi? Fig.9, and i I 7 Hg. 9 adetail section on line 9-9 oi Referring to the drawings 1 designates anaxle, carrying the plates? to which the card holders 3 are pivotallyattached.

The axle 1 has fixed thereon by meansot pin L and screw 4 a bushing 4rtowhich a pair of plates 2 are fixed in any suitable man- 6 nor such as byscrews 5 passing through the plates and threadedly engaging thebush-Pins 6 pro'eet outwardly from the sides eithe bushing to engage holes 7provided in the plates, as shown in Figs. 'l and '8 This provides thateach plate is in proper axial alinement so that the circumferentialapertures 8 in one plate will aline with those inthe otherplate. 7r

The holders 3 are curved or bowed. as shown in Fig. 3, and have adepression to provide a rib 9 in the body portion 10 to strengthen theholder and add rigidity there-- to. The outer end ll and the inner or pirot end E2 of the bodyhavc lateral I'JYOjGCtlOTlS ll, 12, from which theears 'lfiland 1 1- are struck up to engage the bottom 15 and top 16 ofthe card. i At the pivot end ofthe holder-and beyondthe ears 1% theprojections 12 are out I away at 1'? to provide shoulders ISQThe explates so that the holders are spaced from each other. When the holdersattain vertical position, as shown in Fig. 1, only one holder at a timewill fall during rotation of the reel. v a

The holder is also provided with a pair of protnberance s 22 and whichengage the notches Q land 25 of the card 26. This pro vision maintainsthe card in proper position and prevents lateral shifting of the card;

while the cars 13 and i l into which the bottom and top of the card fitpreventinwardor on:

holders are held with the cardinserted there 7 in to be viewed by theoperator.

A pin 31 projecting inwardly from a. post 32 fastened to the bottom ofthe machine adapted to hold a plurality of holders whereby the uppermostcard is held in proper sight position. As the reel revolves the angle ofthe holders in relation to the horizontal axis of the reel becomes lessor sharper and the lowermost holder or the one which rests on the pinwill drop therefrom. This arrange ment provides that the card which isbeing Viewed will remain in proper focus'until a subsequent holdercarrying the nextcard of the series fallsinto si ht position. W' hilethe lowermost holder in each position may not drop simultanenously theywill each drop intermittently in certain spaced time relation to eachother.

In my other application filed concurrently herewith I have constructed amachine which is adapted to show five different series of picture cardsduring one complete revolution of the reel; each series showing thirteendifferent views. It is to be understood, however, that the reel and themechanism controlling it may be made of any size desired and equipped toshow a greater orle ss number of series or it may show only onecontinuous series of cards during the complete revolution of the wheel.

Changes may be made in the form, construction and arrangement of theparts of the invention without departing from the spirit or sacrificingany of the advantages thereof and I reserve the. right to make all suchchanges as fairly fall within the scope of the following claims:
